The global market for electric vehicles (EVs) is experiencing rapid growth, with projections indicating a market volume of $1,084 billion by the end of the decade. One of the key advancements in this sector is the rise of fuel cell electric vehicles (FCEVs) that use hydrogen to power electric motors. FCEVs offer a cleaner and more efficient alternative to traditional combustion engines by utilizing hydrogen fuel cells to produce electricity. Hydrogen is considered a sustainable energy source, particularly when produced using clean methods like electrolysis. This 'green hydrogen' enables FCEVs to achieve lower or zero emissions, addressing climate challenges and reducing harmful pollutants. Furthermore, fuel cells offer cost savings by eliminating the need for battery management and maintenance. With higher efficiencies compared to internal combustion engines, FCEVs are becoming increasingly popular in the transportation sector and beyond. Despite fluctuations in global sales, countries like China and Germany are leading in FCEV adoption, with a growing number of registrations for passenger cars, buses, and trucks. The versatility of hydrogen fuel cells extends to various applications, from powering drones to commercial vehicles and even residential buildings, presenting a promising future for clean and sustainable energy technology.
